Olderst House In Britain Discovered

Oldest House In Britain Discovered To Be 11,500 Years Old -- The Telegraph

Archaeologists have discovered Britain's earliest house dating back 11,500 years.

The home is so old that when it was built Britain was still part of Continental Europe.

The circular structure near Scarborough, North Yorkshire, which dates back to the Stone Age 8,500 years BC, was found next to a former lake.

Our Eavesdropping-On-ET Strategy Not Likely To Work

From Wired Science:

Bad news for SETI: Even with the most sensitive radio telescopes yet designed, humans probably won’t find intelligent aliens by listening in on their phones and televisions, a new study finds.

“Eavesdropping on ET is very hard, even with the latest radio telescopes,” said astronomer Duncan Forgan of the University of Edinburgh, a coauthor of the study. “If we don’t try any other ways of searching for aliens, then we may never find them.”

My Comment: No ET call home I guess.

Men Who Earn Less, Cheat More

Men and women who earn much larger salaries than their partner are more likely to cheat, a new study finds, although women are half as likely to be unfaithful. (Credit: iStockphoto)

From Futurity:

CORNELL (US)—Men who aren’t the primary breadwinners in a relationship are more likely to be unfaithful, according to a new study. But, it’s not about the money, says the lead researcher. It’s about sexual identity.

“Any identity that’s important to you, if you feel it’s threatened, you’re going to engage in behavior that will reinstate your place in that group,” says Christin Munsch, a sociology doctoral candidate at Cornell University. She presented the results of her study at the American Sociological Association’s annual meeting in Atlanta this month.

The U.S. Sniper's More Accurate, Quieter Rifle -- Popular Mechanics

Army Snipers in Afghanistan will receive an improved rifle this fall.

For snipers, every war is different. Recognizing the differences between conditions in Iraq and Afghanistan, the Army is now selecting a contractor to upgrade the 22-year-old Remington bolt-action rifle to become a more effective killing machine. The Army will pour about $5.6 million into upgrades to the M24, with the new gear expected to be delivered to troops by this fall. The M24's barrel is being modified to shoot heavier .300 Winchester Magnum rounds, instead of the 7.62mm NATO ammunition, which should extend the rifle's maximum effective range by hundreds of yards to a maximum of about 1400 yards. The suppressor will reduce the noise and flash of the gun so snipers can stay in their hiding positions much longer after they fire.

'Tissue Paper' Could Stop Bullets, Harness Solar Energy -- Discovery News

Who wouldn't want a shirt that could stop a bullet and power your iPod? A new fabric can do just that.

A soft "tissue paper" made from normally brittle germanium and silicon contains individual fibers as strong as bulletproof Kevlar. Woven into traditional fabric or embedded in hard plastics, the new nanowires could stop bullets, harvest solar energy or perform dozens of other tasks.

Brain-Like Computing On An Organic Molecular Layer

Magnetic resonance images of human brain during different functions appear on top. Similar evolving patterns have been generated on the molecular monolayer one after another (bottom). A snapshot of the evolving pattern for a particular brain function is captured using Scanning Tunneling Microscope at 0.68 V tip bias (scale bar is 6 nm). The input pattern to mimic particular brain function is distinct, and the dynamics of pattern evolution is also typical for a particular brain operation. (Credit: Anirban Bandyopadhyay)

From Science Daily:

ScienceDaily (Apr. 26, 2010) — Information processing circuits in digital computers are static. In our brains, information processing circuits -- neurons -- evolve continuously to solve complex problems. Now, an international research team from Japan and Michigan Technological University has created a similar process of circuit evolution in an organic molecular layer that can solve complex problems. This is the first time a brain-like "evolutionary circuit" has been realized.

From Live Science:

Chimpanzees may gather in hushed quiet to watch a fellow ape in her dying moments, and chimp mothers in the wild may carry their infants' mummified remains for weeks, according to new research on how humanity's closest living relatives deal with the deaths of those closest to them.

Insights into how chimpanzees respond to the death of one of their own are rare. One such instance came with the final hours of Pansy, a chimp more than 50 years old who lived in a Scottish safari park.

The Search For Genes Leads To Unexpected Places

HUNTER Edward M. Marcotte and colleagues at the University of Texas at Austin have found hundreds of genes involved in human disorders. Ben Sklar for The New York Times

From New York Times:

Edward M. Marcotte is looking for drugs that can kill tumors by stopping blood vessel growth, and he and his colleagues at the University of Texas at Austin recently found some good targets — five human genes that are essential for that growth. Now they’re hunting for drugs that can stop those genes from working. Strangely, though, Dr. Marcotte did not discover the new genes in the human genome, nor in lab mice or even fruit flies. He and his colleagues found the genes in yeast.

From Technology Review:

Both Siemens and GE bet on direct-drive generators.

Wind turbine manufacturers are turning away from the industry-standard gearboxes and generators in a bid to boost the reliability and reduce the cost of wind power.

Siemens has begun selling a three-megawatt turbine using a so-called direct-drive system that replaces the conventional high-speed generator with a low-speed generator that eliminates the need for a gearbox. And last month, General Electric announced an investment of 340 million euros in manufacturing facilities to build its own four-megawatt direct-drive turbines for offshore wind farms.

When Will We Be Able To Build Brains Like Ours?

From Scientific American:

Sooner than you think -- and the race has lately caused a 'catfight'.

When physicists puzzle out the workings of some new part of nature, that knowledge can be used to build devices that do amazing things -- airplanes that fly, radios that reach millions of listeners. When we come to understand how brains function, we should become able to build amazing devices with cognitive abilities -- such as cognitive cars that are better at driving than we are because they communicate with other cars and share knowledge on road conditions. In 2008, the National Academy of Engineering chose as one of its grand challenges to reverse-engineer the human brain. When will this happen? Some are predicting that the first wave of results will arrive within the decade, propelled by rapid advances in both brain science and computer science. This sounds astonishing, but it’s becoming increasingly plausible. So plausible, in fact, that the great race to reverse-engineer the brain is already triggering a dispute over historic “firsts.”

The Future For Night Vision Goggles

Night Vision Once the domain of military and police, a cheap thin-film approach to night vision could give cell phones, eyeglasses, and car windshields the ability to see in the dark.

A Cheap, Thin Film Gives Portable Night Vision to Cell Phones and Eyeglasses -- Popular Science

What we regularly refer to as “night vision goggles” are actually less like goggles and more like heavy, bulky (and outrageously expensive) pieces of machinery. But DARPA funded research at the U. of Florida has adapted technology regularly found in flat-screen OLED televisions to create a thin film that turns any infrared signal into visible light, which could integrate cheap night vision tech into car windshields, cell phone cameras and even regular eyeglasses.

From Astrobiology Magazine:

When Pluto was discovered in 1930, it was considered to be the ninth planet of our solar system. Since that time, astronomers have discovered similar icy objects in that far-distant orbital region of the Sun known as the Kuiper belt. Many astronomers questioned whether Pluto should be grouped with worlds like Earth and Jupiter, and in 2006 this debate led the International Astronomical Union (IAU), the recognized authority in naming heavenly objects, to formally re-classify Pluto as a dwarf planet.
